Which one of the following device stores magnetic potential energy in its magnetic field?
Correct answer: C. Inductor
- A. Resistor
- B. Capacitor
- C. Inductor
- D. Thermistor
Explanation
Resistors (option a), capacitors (option b), and thermistors (option d) do not store magnetic potential energy in their components. Resistors dissipate electrical energy in the form of heat due to their resistance. Capacitors store electrical potential energy in an electric field between two conductive plates when they are charged. Thermistors are temperature-sensitive resistors and do not involve the storage of magnetic potential energy.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
